oir-BURNER.

Specification of Letters Patent.

lPatented Mar. 29, 1921.

To cllwhom may concern.'

Be it known that l, RUDOLPH HOFFMAN, a citizen ot the yUnited States, residing at Kankakee, in the county of Kankakee and State ot Illinois, have invented certain new and useful mprovements in Oil-Burners, ot which the following is a specification.

rl`he invention relates to oil burners otL the blue flame. type comprising wick retaining means such as an annular burner bowl or trough connected with a source ot oil supply, and apair of perforated combustion tubes connected together in concentric relation and arranged to be supported upon the trough in operative association with the wick.

ln the use of burners of this general character the combustion tubes are tilted 'from their operative position to permit ot access to the lighting ring. ln this operation, `ditticulty is experienced in properly replacing the combustion tubes upon their seats on the burner bowl. The robject ot this invention is to provide guiding or centering means tor the combustion tubes, ot advantageous construction, for facilitating their replacement into their proper .operative positions after having been tilted or bodily lifted from their seats.

ln the accompanying drawings wherein l have illustrated a. preterred embodiment ot my invention, Figure 1 is a central vertical sectional view through a. burner embodying the features ot my invention, the view being taken inthe plane o't' line 1-1 of Fig. 2. Fig. 2 is a horizontal section taken on line 2-2 of VFig. 1. Fig. 3 isa detached eleva tion showing the parts of the guiding means in position to be assembled. T he burner as herein illustrated comprises an annular bowl or trough 1 having a wick or lighting ring 2 therein ot asbestos or the like. Said trough communicates at 3 with a suitable source ot oil supply (not shown). et and 5 indicate perforated combustion tubes for the burner secured together in concentric relation by any well-known means (not shown) and adapted to be seated upon the trough 1 in operative association with the wick 2. To this end the upper edges of the trough 1 are provided with oppositely projecting horizontal flanges G and 7 formed integral with the walls ot the trough. Preferably said flanges are disposed slightly below the upper edges of the trough so as to prevent lateral movement ot the combustion tubes relative thereto.

The guiding and vcentering means tor the combustion tubes comprises a plurality of radially extending arms or Wings carried by the trough 1. Herein, said wings are formed by two angular members 8 and 8a, each providing two wings disposed substantially 900 apart, and the wings of each member are connected together by straps 9 and 10. These straps are so arranged as to interit to 'form a central socket 11 tor receiving a retaining pin 12, the opposite ends of which may be bent as at 13 and 14 to prevent its removal from its operative position. ln worder that the upper end ot the pin 12 shall not project upwardly above the upper edges of the wings the upper strap 10 of the wing member 8@ is notched as at 15. The upper edges ot' the wings are inc-lined downwardly and outwardly and their upper outer edges are rounded as at 16 with their outer upright edges disposed a short interval inwardly ot the vertical plane of the wick 2. Said upright edges of the wings thus guide the inner combustion tube and thereby the outer tube connected therewith, centering the tubes relative to the trough 1 and wick 2. Notches 17 are formed in the outer edge of each wing near the lower portion thereof, and the portions 18 of the wing below said notches are extended outwardly so that when theparts are in operative position the eX- tended aortions engage with the inner wall of the burner trough 1.

ln assembling the guiding means, the two wing members 8 and 8 are placed oppositely within the burner trough 1 with the outer edges ot the wings engaging the inner surtace ot the trough and the Flange 7 of the trough entered in 'the notches 17. At their inner or central portions the members are brought together so that the straps 9 and l() intertit to form the socket 11, and the pin 12 is inserted into the socket and its ends bent to lock the parts in position. The parts are so proportioned and arranged that when in operative position the wing members interengage and abut the trough 1 whereby relative movement and play between the parts is prevented and the wings are held spaced apart in substantially equidistant relation.

1t will be seen that l have provided a burner with guiding means tor the combus- Cac tion ,tubes of an advantageous character. The paucity and simplicity of the parts lends cheapness to the device, it doesV not interfere with the operation of the burner, and may be readily assembled or disassembled when desired.

I claim as my invention:

1. An oil burner comprising, in combination, wick retaining means having an annular flange, a combustion tube'arranged to be seated upon said flange, two pairs oi wings, each pair connected by one or more straps adapted to interit to iorm a central socket, and a pin. entered into said socket to secure the wings together, the outer edges of said wings detachably engaging and supporting said wings upon said wick retaining means, said wings being adapted to guide said combustion tube toward and from its seat.

2. An oil burner comprising, in combination with a combustion tube and a seat therefor, means for guiding the tube to a position upon its seat comprising a plurality of wings spaced apart and connected togethern at their inner edges with their outer edges operatively engaging said seat so as to restrain upward and downward movement of said wings.

3. The combination with a pair of combustion tubes and horizontal flanges forming supports therefor, of means for guiding the combustion tubes into position upon their seats comprising two angular members each providing a pair of wings and detachably connected together at the inner edges of the wings and to one of said flanges at the outer edges of the wings.

4.. In an oil burner, in combination with a combustion tube and an annular seat therefor, of means for guiding the combustion tube toward and from its operative position upon said seat comprising a plurality of wings, and means at the inner edges of said wings securing them together in spaced relation, the outer edges of said wings being notched to receive said annular seat member and secure said wings against upward or downward movement.

5. In an oil burner, the combination with a combustion tube and an annular seat member therefor, of means for guiding the combustion tube vertically relative to said seat member comprising a plurality of members providing a plurality of wings the outer edges of which are adapted to operatively engage and support said wing members upon said seat member, and means for securing the inner portions of said wing members together.

6. In an oil burner, the combination with annular wick-retainingV means and a combustion tube arranged to be supported thereby, of means for guiding the combustion tube relative to the wick comprising a plurality of radially extending members supported against removal by the wick-retaining means and having guiding edges for centering the lower end vof the combustion tube relative to said wick-retaining means.

7. In an oil burner, the combination with wicloretaining means and a combustion tube supported in operative association with the wick of means for guiding the combustion tube relative to its support comprising a plurality of upright members secured to the wick-retaining means and having upright guiding edges located adjacent the vertical inner periphery of the wick.

8. The combination with a pair of combustion tubes and horizontal annular flanges forming supports therefor', of means for guiding the combustion tubes into position upon their seats comprising two angular members each having a pair of wings and connected at their angular portions by a pintle, said wings having notches in their outer edges to receive the supporting flange for the inner combustion tube.V l

9.` In an oil burner, the combination with a tiltable combustion tube and an annular seat member therefor, of means for guiding the combustion tube in yseating it on said seat member comprising a plurality of angularly arranged pairs of wing members connected at their angular portions by a pintle and secured to said seat member, said wings having curved edges adapted to engage and guide said tube to its seat.

In testimony whereof, I have hereunto set my hand.

RUDOLPH HOFFMAN.
